[PATCH v4 7/8] winex11.drv: Release pointer grab on FocusOut events.

[Rémi Bernon]

When a window receives FocusOut event, whether it is because the WM is
grabbing the keyboard or because of an actual input focus change, we
should release the pointer grab.

We will re-apply it on FocusIn event if it is necessary from Wine's
perspective.
